Configure Ticker with Alpaca Portfolio

[tbeseda]

I made a quick Node CLI to populate Ticker's .ticker.yaml lots option with current positions from Alpaca.

alpaca-ticker-config on npmjs.org + documentation
source on github

I've listed some next steps under "Todo" in the README.

Probably a narrow set of users here, but it may be helpful for watching your Alpaca portfolio. 👍🏻

This is awesome! It's great to see community built integrations for ticker. I'll add a section in the readme referencing this.
